HAIR-CURLING APPARATUS.

' Application filed October 5, 1925. YSerial No. 60,448.

This invention relatesto apparatusfor treating and curling hairandinore particularly to a device for giving permanentwaves upon humanhair.

1t is an objectl of this invention to provide in apparatusvv for curling hair, improved curling units adapted to bev utilized in connectioii with any standardtypeofsupporting bracket and adjusting mechanism.

Another object of theinvention is to provide a highly efficient heating unit flexibly and adjustably supported from said bracket including a tubular housing, a curlingr rod insertable therein and highly elficien't means for retaining and centering said rod within said housing and means for protecting the hair and scalp treated in the process of efi fecting permanent waves.

A. more specific object ofthe inventionv is to provide hair curling apparatus comprisingl a depending chandelier having means-for guiding and adjustablyV supporting aY plural-` ity of heating unitsI connected theretov byy means of flexible electric conductors, whereby said' heat-ing units, in depending position,

will bedisposed in a figure encircling the head of the person to be treated and-willnot tend to become tangled with each other.

A still further object in such apparatus is to provide a plurality ofhe'ating devices, each comprising a tubular casing', a curling rod carrying a protective shield at its lower end and efficient means for centering and retaining the vupper and'lower ends Vof said rod within said casing. i, y

These and other objects of the invention n will'be apparent from the following description made in connection with the accompa-nyforming the resilient retaining socket of the preferred form ofthe heating device ;`and

Fig. 5 is a fragmentary vertical section of the lower portion of a modified form of the heating device. y

Referring to the drawings, a radial arm 12- of an overhead support is illustrated carrying at its outer end a trough-like frame member '13 inwhich a. plurality of electric sockets 14 are housed' and secured, the contacts of said sockets being'aecessible from the bottom of trough 18. Sockets'14 are connected to a source of electricity, suitable switches (not shown) being provided, and ai pilotv light 15a is also carried by arm 12A con-r nected in circuit with said socketto indicate whether or not said circuit is closed or open. A detachable cover plate 16 closes the top of' trough member 13 and arm 12.

Disposed above the supporting bracket .is

a. bracket having radially extending arms' 17 carrying suitable guide members y18 and `19 having oppositely alined radially arranged apertures therethrough,through which cords orv flexible connections 22a are passed, the outer ends of said' connections being securedn to electrical connections 20 which connectl the sockets 19 with the heating or curling devices. lCounterweights'y22 are secured to the inner falls of flexible members 22VB adapted to balance said vheating devices in desiredV positions. of trough'members 13 resilient U-shaped retaining clips 23 are secured, each adapted to engage one of the heating devicesto retain the same in compact inoperative position.

The preferred form of heating devices, asv

illustrated in Figs. `1 to 4, inclusive, comprises. an elongated tubular casing 25 having seated within its upper or inner end a *resilient socket or retaining member26 formed,

preferably, from a blank, as illustrated` in" Fig. 4. A cap member 27, preferably of some compressible heat resistant material,

such as cork, is disposed over the upper end of the casing 25', holdingthe resilient socket 26 in proper operative position. ber 27 is providedat either side with a 10ngitudinallykextending slot 27a in which the fieXible lelectric connections 2O are disposed, connections 2 0 passing through an annular spacer28 secured-about the intermediate portion of casing 25.

On the peripheral edge.

vCap mem- The spacer 28 has se-v cured thereto the upper endV of a housing 29 enclosing a standard form of electric heating coil 30. The lower extremities of electric connections are knotted below spacing member 28.

. heat resistant material and adapted to close the lower or outer end of tubular casing 25, when the rod 3l is inserted therein in operative position. Shield member 32 has preferably the projecting plug portion adapted to'ifit snugly within the lower end of tube to actas a stopper therefor and to centerthe lower end of rod 231. rlhe plug portion'of shield 32 is preferably recessed and secured to the lower end of rod 3l by means of a transverse pin. strand of hair, indicated by the letter X, to bev curled on rod 31, a slot 32 is formed in shield32 extending from a peripheral edge thereof inwardly and having an enlarged mouth portion and a substantially round receiving portion. Obviously a strand of hair may be easily forced into the receiving portion of slot 32a adjacent the scalp and retained therein and the ,free end of said strand may then be carefully wound on curlingiod 31 and inserted in operative position within tubular casing 25. The shield member 32 is shown as equipped with a relatively small cleat 321 secured to the under side thereof and adapted to retain a string or other flexible member :c tied tightly around a strand of hair, thereby further securing the hair against longitudinal displacement when coiled on the rod 3l.

1t will, of course` be understood that the resilient socket 26 may be formed Of a plurality ofindependent leaf springs or in any other suitable manner and that the shield member may be of other suitable forms, such as al stopper, and that a cleat or other string retaining means may be 'employed or dislpensed with thereon, as desired, all within the scope of this invention. f

In Fig.' 5, a modified form of the heating device is shown, having the tubular casing 25 and a curling rod 33 adapted to be disposed therein,v said curling rod rigidly carrying the rshield 34 at its lower end. The shield and rod are secured to the lower or outer end of tubular casing 25 by means of a pair of -leaf springs 85 secured adjacent the outer flanges of said shield, equipped with small retaining members 35 adapted to engage notches or holes in the lower portion of tubular `casing 25. 1n this form of the in- 'l`o permit a1 vention, as in the preferred form, the lower portion of the curling rod is centered and held in operative position by mutually en-V gaging parts on the lower end of the tubular casing and the shield member.

Operation.

ln effecting permanent waves upon human hair, the person to be treated is disposed or seated beneath the bracket, with the axis of the head substantially centered thereun der. The heating devices are then released, asl desired, from their retaining members 23 and depend in a ligure encirclingthe head. Strands of hair areseparated on the head and each strand is inserted adjacent the scalp through the slot '32a in one of the shield members 32, the hair being further secured to the lower end of the curling rod 31, if desired, by means of the string' az" wounr'l lightly thereabout and secured'in the cleat 32". Each strand of hair having been treated Awith oil is then wound upon a curling rod 31 and the curl Vtightened by twisting said rod, as desired. The upperv endvof each stiandis tightened or otherwise secured adjacent the upper end of rod 3l and the rod carrying the plug shield member 32 is then inserted within the tubular casing 25, the upper end of rod 31 therebybeing engaged by the resilient socket 26 and centered and retained in operative position. TheA plugl portion of shield 32 `will also assist in centering aiid retaining the lower endof rod 31 to casing 25. yThe curlingprod 31 may, of course, be employed within the scope of this invention without the plug-like shield carried at its lower end.

causing permanent waves, inasmuch as the curling rod is longitudinally centered within tubular casing 25 and is securely retained therein. The cork cap members 27, having means for countersinking conducting wires 20, permit the operator to manipulate the several heating devices without injury to their hands, andthe plug shields` substantially close the ends of tubes 25 retaining the hot oil vapor therein.

From the foregoing description, Vit will be` seen that the applicant has invented simple Vbut highly efficient apparatus for Ycurling human hair and effecting permanent waves thereon. Vrlhe device has been put to actual usage and has proved highly successful for all the purposes intended. y

It, of course, will be understood that various changes and omissions may be made in the form, details, proportions and arrangement of parts without departing from the scope of the invention.
